WORK-FEEDING MECHANISM FOR CHANNELING-MACHINES.

Application filed November 15, 1917.

To all whom it may concern:

iie it known that I, FELIX E. VALo1s, a citizen of the l nited States, residing at Havel-hill, in the county of Essex and State invented certain of Massachusetts, have new and useful Improvements in Work- Feeding Mechanism for Channeling-Machines, of which the following is a specilication, reference being had therein to the accompanying drawings.

This invention relates to shoe machines and more especially to a device or attachment for feeding the work to the channeling knife of a sole-ehanneling machine.

In such machines as heretofore ronstrut-ted a. power driven shaft is employed for positively rotating the feed wheel, such shaft being spaced at some distance above the knife, a'ieed Wheel of relatively large diameter being employed and fixed directly upon the shaft.

is so constructed, machines of this type have proven faulty in operation, especially when employed upon an extremely pointed style of sole, the large feed wheel having so long a bearing surface upon the work as to cause diliirulty in turning the work rapidly, as in going around the toe.

It is an object of the present invention to overcome the above difiiculty by the provision of a feed Wheel much smaller in diameter than is at present employed.

It is a further ObJGCl) of the invention to provide in a machine of the above type an attachment applicable to the existing form of machine Without change. which shall permit of the use of a feed Wheel of small diameter.

The above objects are obtained by the merhanism hereinafter more fully described and illustrated in the annexed drawings, it being understood, however, that the specific arrangement of parts shown is only by Way of example and that any and all changes therein Within the province-of mechanical skill are to be incfuded Within the scope of the annexed claims. I

In the drawings Figure l is a perspective showing the attachment located with relation to the Work table of the machine, Fig. 2 is a side elevation of the attachment, with parts broken away to show the interior arrangement, and Fig. 3 is an edge view ofthe same, partly in section.

This invention is intended to be applied Specification of Letters Patent.

Patented Aug. 10. 1920. Serial No. 202,136.

the general type of that to French, 453,991), June 9, 1891, to which patent reference may be had for a fuller disclosure of the general machine construction, the present invention relating entirely to the feed-wheel therefor, and means for driving the same.

1 is the frame of the machine having mounted upon the same a rotary worksupport or table 2. arranged to turn about its center 3 upon a suitable pivoting device. At 4. is indicated the usual feed-drive shaft employed in machines of this character, said shaft being driven constantly from any suitable source of power. At 5 is shown an opensided receptacle provided with threaded openings (3 whereby the same may be attached to the frame of machines of the existing type, said receptacle being provided with a cover-plate T removably attached thereto and adapted to close the open side thereof. in the cover 7 of the receptacle is formed an opening 8, and opposite the same in the base of the re'cptacle formed an alined bearing opening 9. said openings being arranged for the reception of the drive-sha ft 4.

Surrounding the shaft 4 and journaled within the bearing 9 is a sleeve 10, said sleeve being integral with a gear-wheel ll, which is located within the casing, the shaft 4 and the sleeve 10 being connected to turn together as by means of a key 12 or other equivalent device. 13 indicates a stub-shaft projecting substantially across the interior of the casing and fixed to the base-member 14 thereof, said stub-shaft having mounted to turn thereon a gear 15 meshing with the gear 11. At 16 is a second stub-shaft secured in any suitable way in an opening in the base member 14 and extending substantially across the interior of the casing. 17 is an enlarged opening in the cover plate 7. said opening being concentric with the stubshaft 16. Mounted to turn freely upon stub-shaft 16 is. a gear-member 18, said gear-member having integral therewith or suitably attached thereto a disk 19 provided with toothed edges as shown at 20, and com stituting the feed-wheel for feeding the work past the channeling tools.

As herein shown the Wheel 19 is located upon the outside of the casing. the connecting portion of the gear 18 passing through the opening 17 in the cover-plate. It is to to a machine of shown in patent lit) be understood, however, that it is Within the scope of the resent invention to locate the feed-wheel within the casing permitting the edge thereof to project through a suit able slot beyond the lower face of the casing, no specific claims, however, being made to this latter form of the device.

The operation of the attachment will now be clear. The receptacle 5 having been properly positioned upon the frame of the machine with the drive-shaft 4 passing within the sleeve 10 and fixed thereto, upon rotation of the drive-shaft, the feed-wheel through the intermediate gear connections will be rotated at the same or greater speed than that of the drive-shaft. It is often desirable that the gears be so proportioned as to make the feed speed the same as that of the usual large feed wheel, particularly where the work support is positively driven. By reason of the above arrangementit has been made possible to substitute for the large feed-wheel, IfOUIIUUDlZV employed in machines of this character and such as is shown in the patent to French above noted, a wheel of much smaller diameter without necessitating any change in the location of the drive shaft or its connected parts. As has been pointed out above, the feed-wheel of smaller diameter offers many advantages over the large wheel, particularly when employed upon work in which it is necessary to sud denly vary the angle of the work in presenting it to the knife, as for example, as going around a toe of very pointed form.

\Vhile the above is a preferred form of the device, it is to be understood that the lHYQl'k tion is not to be limited to the exact details of construction shown, but is to be con strued as embracing all equivalents thereof falling within the scope of the appended claims.

Having thus described the invention and the operation thereof what I claim and desire to secure by Letters Patent of the United States is:

1. In a machine of the class described, a feeding mechanism consisting of an abutment to support the work, a feed shaft arranged to carry a feed wheel, a feed wheel of substantially smaller radius than the distance between said shaft and the surface of the work supported on said abutment, and means for driving said wheel from said shaft.

2. A work feeding attachment for a ma chine having a work support and a feed shaft arranged to carry a feed wheel, said attachment consisting of a feed wheel of substantially smaller radius than the distance between said work support and said feed shaft, and means for driving said wheel from said shaft.

3. A work feeding attachment for a machine having a work support and a feed shaft arranged to carry a feed wheel, said attachment consisting of a casing adapted to be carried on said feed shaft, a stud shaft fixed within said casing, a gear free to rotate upon said shaft, a toothed feed wheel connected to rotate with said gear and having its work-engaging edge extending beyond said casing, and a gear on said feed shaft arranged to rotate therewith and to drive said first mentioned gear.

4. A feed attachment for channeling machines comprising, in combination, a boielike casing or receptacle having a detachable cover, with an opening therein, a stub-shaft fixed in the opposite wall of the casing and mncentric with said opening, a combined gear and feed-wheel loosely mounted upon said shaft and extending through said opening, a second stub-shaft within the casing, a second gear mounted thereon and meshing with said first gear, and a power shaft journaled within opposed openings in said'casing and having fixed thereto a gear meshing with said second gear.

I). In an innersolcchanneling machine having a work-table and a power driven feed-shaft, a receptacle or casing having opposed journal openings in its walls for the reception of said shaft, a gear fixed upon said shaft and within the casing, a stub shaft journalcd in said casing and having a gear free to turn thereon and within the casing, a toothed feed-wheel fixed to said second gear and having its edge in close proximity to said work-table, and a third gear within the casing and meshing with both of the aforementioned gears.

6. A feeding attachment for a machine having a Work support and a feed shaft arranged to carry a feed wheel, said attach.- ment consisting of a feed member having a work engaging surface, the extent of contact of said surface with the work in the direction of feed being substantially at all times less than that of a feed wheel of a radius substantially equal to the distance between the feed shaft and the work support, and means for actuating said feed member from said shaft. g

In testimony whereof I have signed my name to this specification.

FELIX E. VALOIS.
